DRS (Dynamic Resolution System) Res-Spd/ Res- Pen
DRS is a macro control that provides instantaneous one button adjustment
of temporal vs. spatial resolution in 2D, 3D, color and CPA modes. The
feature is designed to give the user the best combinations of multiple
controls when they need to choose between fast frame rates or optimal
image quality.

DRS (Dynamic Resolution System) Res-Spd / Res- Pen
Dynamic Resolution System - one control that adjusts nearly 40
parameters simultaneously to optimize functions such as:
· Line density , Persistence, Number of lines of sight (SonoCT)…
R1 is optimized
for maximum
image quality
R1 is optimized for
color resolution
RS provides the
best overall choice
of system settings
P1 is optimized for
color sensitivity
S1 is optimized to

AGC ( Adaptive Gain Compensation )
AGC works continuously to correct for localized attenuation
and enhancement variations not accounted for by Time Gain
Compensation (TGC). AGC does not control overall gain or
compression. AGC is hardware controlled and there is no
effect to frame rate when activated.
While AGC is activated all
other controls (TGC, gain, etc.)
will respond normally.

iSCAN
•Uses system intelligence to
automatically adjust:
–TGC based on tissue
attenuation
–Receiver gain based on
overall tissue brightness
–Re-map compression
curve based on range of
detectable tissue signals
–Doppler gain based on
Doppler signal strength
–Doppler PRF based on
maximum detectable
velocity
–Doppler Baseline based on
forward/reverse flow
components

Philips Technology
How does AGC differ from iSCAN?
iSCAN is an automated image optimization process using
user-available controls (gain, TGC, compression). iSCAN
optimizes the image each time the Iscan button is
pressed. The purpose of iSCAN is global image
optimization.
AGC is a signal processing technique that dynamically
adjusts the gain of every sample in real time. AGC runs
continuously when activated. The purpose of AGC is
dynamic correction of localized gain artifacts.

Imaging Modes
CPA ( Color Power Angio )
- an amplitude mode color display showing the
intensity of Doppler shifts. CPA is useful for showing
slow or diminished flow due to the fact that it is less
angle dependent than color flow imaging.
